Ringkasan	Magnetic Resonance Elastography (MRE) is a non-invasive imaging technique that measures tissue stiffness by encoding the motion of acoustic shear waves into MRI signal and calculating the elastic modulus from wave propagation patterns. Developed by Muthupillai and colleagues in 1995, MRE enables quantitative assessment of tissue mechanics, particularly useful for diagnosing liver fibrosis, cardiac dysfunction, and neurological diseases. It has emerged as a non-invasive alternative to biopsy for staging hepatic fibrosis and is expanding into other organ systems.	Optical Coherence Tomography Angiography (OCTA) is a non-invasive imaging technique that visualizes the microvasculature in the retina and choroid by detecting motion contrast from flowing blood. Developed by Jia and colleagues in 2012, OCTA uses repeated OCT scans of the same tissue location to identify blood flow based on the decorrelation signal. It has become a critical diagnostic tool in ophthalmology for detecting retinal and macular diseases without requiring fluorescein injection.
